It’s important to check the label for any additional ingredients that could impact the calorie content.

The size of the tuna serving also matters when determining the calorie count. Larger portions will naturally contain more calories than smaller servings. Furthermore, the freshness of the tuna can impact its nutritional value, so opting for fresh or high-quality canned tuna can make a difference in the overall calorie content.

Opting for tuna in water can be a better choice for individuals looking to maintain a lower calorie diet without sacrificing protein intake.
